This could be an interesting opinion if you added some logic to it and try to explain why you think China would leave something they were one of the main founders of and is benefiting them greatly.
China founded BRICS because nobody was inviting it to the “grown-ups club” — the G7. Developed countries still don’t see China as an equal. At some point, Xi Jinping, wearing his ‘eternal Mao’ suit, decided to flex muscles by expanding BRICS with a bunch of raw-material satellites — to shake the dollar’s dominance.
But the moment this expansion started smelling like real responsibility and potential loss of access to US and EU markets, China quietly stepped back. That’s how it works.
China is considered one of the founders of BRICS, so I think it is completely unreasonable to think that China will back. China is the most active in the expansion of BRICS and this country is leading all the others and always wants BRICS to become more powerful in the future. You know that among all the BRICS countries, China is the only one that is the most powerful and will be the most profitable if it comes out of the Western regime. Currently, there is a competition between US and China in terms of trade and commerce. If the BRICS is successful, then indirectly China will be able to lead the BRICS. So it is worth less to think that China will go back from BRICS.
Chinese President Xi Jinping himself is committed to being involved in it he says :
We BRICS countries share extensive consensus and common goals. No matter how the international situation changes, our commitment to cooperation since the very beginning and our common aspiration will not change.The reason why China is creating BRICS is that they do not want to depend on the US or the EU. They know very well that the US president can increase trade tariffs at any time according to his wishes. We have also been aware of this. When the US increased tariffs, China also responded by increasing tariffs. So they will not do any business with them out of fear.
The purpose of forming BRICS against the US and Western regimes is so that China can maintain its dominance. If China is not active here, then there would be no need for other countries to form BRICS. If BRICS is established, all the countries in its alliance will benefit, but China will be the most profitable. If this is the case, then why would China leave from BRICS?
